Title: ForestPack 7 Scattered Lights Limitations with vRay
Post by: Rokas on January 12, 2021, 11:08:02 AM
Dear V-Ray and Forest Pack users,
As you may have seen, the upcoming version of Forest Pack will be able to scatter lights. We believe this will open the plugin up to many exciting new workflows, in fact, we've already seen some fantastic stuff by some of our beta testers. If you fancy trying it out then the installer is publicly available to all users with an active maintenance plan, but before you dive in, we wanted to mention a couple of limitations that V-Ray users should be aware of.

1. First of all, instanced lights aren't working with VRayMultiSubTex or Forest Pack colour. We're working with Chaos Group to resolve this (Chaos Group Ticket VMAX-8645):
This means at the moment that you're not able to use a Forest Color map to randomise the light colour or intensity (as a workaround, you could try scattering multiple lights with different settings).

2. Secondly, lights can't be animated and will take their transforms and parameters from the first frame (ChaosGroup Ticket VMAX-10079).

                          How it works now                                              Expected result

We're working with Chaos group to resolve both these small limitations, but in the meantime, we hope you find the new light scattering features really handy.
Please feel free to let us know in this thread (https://forums.chaosgroup.com/forum/v-ray-for-3ds-max-forums/v-ray-for-3ds-max-general/1098545-forestpack-7-scattered-lights-limitations) how you get on, what you like, what you don't, and any issues that you spot.

Many thanks,
The iToo Software team.

I noticed that light scattering is not supported on Vray for GPU.
Will it be available with the official release?

Best

Hi.

We're currently working with Chaos Group because there are a few changes needed on their side to fully support scattering lights. They've already started work on the changes that we'd need. At this point we're not clear if this will also apply to the GPU engine and support for this version is taken care of by Chaos Group themselves using our API.  We hope to know more soon about how what exact features will be available (Forest Color / Light Mix / animated transforms) on what engine (CPU/GPU) as the work progresses.

There is also a thead on the Chaos Group forum  (https://forums.chaosgroup.com/forum/v-ray-for-3ds-max-forums/v-ray-for-3ds-max-general/1098545-forestpack-7-scattered-lights-limitations)where you are welcome to ask this question, as you may get a more detailed update.
